A third plane can he found that passes through the line of intersection of two existing planes. (4 marks) a. Two planes are given by the equations 33 53; l 22: 8 = D and 42: l 23; + 3.2: l 11 = 0. Find the scalar equation of the plane that passes through the line of intersection of these two planes, and also passes through the point (2, 3, 4}. b. Give the equations of two planes. Create a third plane that passes through the line of intersection of the original two and which is parallel to the air-axis. Explain your reasoning and include a LanGraph of your planes
